how to enable cache-status,hits,hit-ratio attributes defined in infinispan

[rituraj]

going through the cli command i saw a lot of attributes which are not available or may be i missed but where can i activate them

"outcome" => "success",

    "result" => {

        "description" => "A distributed cache",

        "attributes" => {

            "cache-status" => {

                "type" => STRING,

                "description" => "The status of the cache component. May return null if the cache is not started.",

                "expressions-allowed" => false,

                "nillable" => true,

                "min-length" => 1L,

                "max-length" => 2147483647L,

                "access-type" => "metric",

                "storage" => "runtime"

            "hits" => {

                "type" => LONG,

                "description" => "The number of cache attribute hits. May return null if the cache is not started.",

                "expressions-allowed" => false,

                "nillable" => true,

                "access-type" => "metric",

                "storage" => "runtime"

            },

            "hit-ratio" => {

                "type" => DOUBLE,

                "description" => "The hit/miss ratio for the cache (hits/hits+misses). May return null if the cache is not started.",

                "expressions-allowed" => false,

                "nillable" => true,

                "access-type" => "metric",

                "storage" => "runtime"

            },

            "remove-misses" => {

                "type" => LONG,

                "description" => "The number of cache attribute remove misses. May return null if the cache is not started.",

                "expressions-allowed" => false,

                "nillable" => true,

                "access-type" => "metric",

                "storage" => "runtime"

            },

            "misses" => {

                "type" => LONG,

                "description" => "The number of cache attribute misses. May return null if the cache is not started.",

                "expressions-allowed" => false,

                "nillable" => true,

                "access-type" => "metric",

                "storage" => "runtime"

            },

so basically i am looking here

ls

These metrics will be undefined if the target cache is not started.  For the "web" cache container, these cache containers are started automatically when a <distributable/> web application is deployed.

[rituraj]

Hi Paul,

Thanks for replying ...we are using domain mode and dist mode for infinispan caching for me everything looks running  ...and most probably i am not looking it correctly

to resolve this
"These metrics will be undefined if the target cache is not started."
where should i check ...any parameter or value or anything how to start this "target cache"
Also we have a distributable war deployed as well..

Thanks
Rituraj

Hi Paul,

i am still not able to find out where i am missing ....below things i have checked and are running
1) a distributable war has been deployed on servergroup
2) we are using HA profile in domain mode
3) infinispan configuration is below

                <cache-container name="web" default-cache="dist"  module="org.wildfly.clustering.web.infinispan" statistics-enabled="true">

                <transport cluster="${jboss.cluster.name}" lock-timeout="300000"/>

         <distributed-cache name="dist" batching="true" statistics-enabled="true" mode="SYNC" remote-timeout="300000" owners="${jboss.owner.value}" l1-lifespan="0">

                        <state-transfer timeout="300000"/>

                        <file-store/>

                    </distributed-cache>

                </cache-container>

4) we have checked the session replication is working ...
but i am still unable to see anything in the above value for infinispan subsystem  ....please let me know if i am missing anything or need to check anything here ....

there are other things as well which i am not sure why they are undefined for example
/profile=ha/subsystem=infinispan/cache-container=web

cache-manager-status=undefined  as per the description description" => "The status of the cache manager component. May return null if the cache manager is not started."

if all the above are enabled via deploying a distributable war then we are already doing it ...then why i am getting these values as undefined ..?
please help ....

Thanks

Did you enable statistics for infinispan subsystem? they are off by default.

[rituraj]

Hi Tomaz,

Thanks for replying !!
yes they are enabled ...i have checked it here

also they are enabled in the dist cache as well(as we are using dist)

string-keyed-jdbc-store             indexing-properties=undefined       read-write-ratio=undefined          virtual-nodes=1

let me know if i have to look somewhere else as well

By default, the read-resource operation does not include runtime-only attributes.

e.g. The operation:

[standalone@localhost:9990 /] /subsystem=infinispan/cache-container=server/replicated-cache=default:read-resource(include-runtime=true, attributes-only=true)

Outputs the following:

{
    "outcome" => "success",
    "result" => {
        "activations" => 0L,
        "async-marshalling" => undefined,
        "average-read-time" => 0L,
        "average-replication-time" => 0L,
        "average-write-time" => 0L,
        "batching" => undefined,
        "cache-status" => "RUNNING",
        "elapsed-time" => 247L,
        "hit-ratio" => 0.0,
        "hits" => 0L,
        "indexing" => undefined,
        "indexing-properties" => undefined,
        "invalidations" => 0L,
        "jndi-name" => undefined,
        "misses" => 0L,
        "mode" => "SYNC",
        "module" => undefined,
        "number-of-entries" => 0,
        "passivations" => "",
        "queue-flush-interval" => undefined,
        "queue-size" => undefined,
        "read-write-ratio" => 0.0,
        "remote-timeout" => undefined,
        "remove-hits" => 0L,
        "remove-misses" => 0L,
        "replication-count" => 0L,
        "replication-failures" => 0L,
        "start" => "EAGER",
        "statistics-enabled" => true,
        "stores" => 0L,
        "success-ratio" => "N/A",
        "time-since-reset" => 247L
    }
}

Hi Paul,

I have configured a standalone configuration on WF-8.1.0 and deployed the same war there as well to check the values ...i can see those values as you said but
in domain mode these values are not available and working in standalone only
can you please check from your side as well?

Thanks
-Rituraj

[rituraj]

Hi Paul,

This seems to be not working in domain mode and works only in standalone ...is there a workaround ?
also is there a potential issue with infinispan if its not showing up the values what do we need to do ?

Thanks

Rituraj

[rituraj]

any updates ?
looks like these metrics are not coming in domain mode ...

Hello Rituraj

You've done everything right to enable statistics; your only error is from which addressable resource you are expecting to find the metrics for a given server in the domain.

The resource /profile=ha/subsystem=infinispan/ represents the configured values for the infinispan subsystem (and its children) in the ha profile. This resource and its children will not contain metrics for the infinispan subsystem for any specific server instance, rather common domain configuration information for that profile.

To find server instance specific metrics, you need to specify which server you want (i.e. which host and which server name) and then read the infinispan resource on that server. So your addressable resource needs to be:

/host=<hostname>/server=<server-name>/subsystem=infinispan

So, for the default Wildfly 8 domain configuration, the command to see the metrics for the web cache container on server instance server-three on host master looks like this:

/host=master/server=server-three/subsystem=infinispan/cache-container=web:read-resource(include-runtime=true)

The metric values you expect will now appear.

Here is a convenience CLI command to actually enable statistics in domain mode via CLI (same result as changing xml manually):

[domain@localhost:9990 /] /profile=ha/subsystem=infinispan/cache-container=server:write-attribute(name=statistics-enabled,value=true)
{
    "outcome" => "success",
    "result" => undefined,
    "server-groups" => undefined
}

[rituraj]

Thanks Rado and Richard
although i have enabled the statistics but was looking in the wrong place ...
Richard : thanks for pointing out the correct location ...basically we are using web cache container with distributed-cache and wanted to look for the details ....

if someone needs to look for the same in domain mode try the following command

[domain@localhost:9990 distributed-cache=dist] ls /host=hostname/server=servername/subsystem=infinispan/cache-container=web/distributed-cache=dist
